The remaining pendants are all made of shell. The one shown in Fig. 87 is a natural olivella shell with the top of the cone missing and found in grave No. 39 (1) of a child in a rock-slide near the head of Priest Rapids. A shell somewhat similar to this made into a bead was found in the Nez Perce region.[280] The pendant shown in Fig. 88 was found in the grave of a child in a rock-slide west of the Columbia River near the head of Priest Rapids. It is made of a small marine clam shell (_Pectunculus_), probably a young _Pectunculus gigantea_. The perforation passes through the apex and has apparently been gouged from the outside. The ribs on the convex surface of the shell have been nearly effaced by grinding or polishing and the hinge also seems to have been smoothed so that only slight scars mark the depths of the teeth. This shell certainly came from the Pacific Coast either in its natural condition or after having been made into this form. It is the only object made of this kind of shell which I have seen in the whole northwest. The pendant shown in Fig. 89 is made of iridescent shell possibly unio but probably haliotis. If the latter, it must have come from the Pacific Coast. It was found in the same grave. This grave contained no objects of white man's manufacture or anything suggesting that it was modern. A list of its contents will be found on p. 169. This pendant is of the form of an isosceles triangle. It is perforated through the more acute angle by a small hole which tapers as if drilled from each side of the object. The edges of the pendant are rather sharp in places and the lower one is concave in outline. This object may be compared with the pendant made of bone, found at Lytton,[281] which was considered to be a sap scraper.[282] [280] Spinden, Plate IX, Fig. 14. [281] Smith, (d), Fig. 95.
